WILLIAM R. FREDERICK, OF FORT WAYNE, INDIANA.

EXHAUST-NOZZLE.

SPECIFIGA'IION forming part of Letters Patent No. 657,101, dated September 4, 1900. Application filed May 2, 1900. Serial No. 15,180. (No model.)

To atZZ whom it may concern:

Be it known that I, WILLIAM R. FREDERICK,-

a citizen of the United States, residing at Fort WVayn e, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Exhaust Nozzles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in exhaust-nozzles wherein means are employed to increase ordecrease the discharge-opening; and the object of my improvement is to provide means for automatically adjusting the eXhaust-openin g according to the quantity of the discharge. I accomplish my object by the construction illustrated in the accompanying drawings, in which- Figure 1 is a side elevation, partly in section, and Fig. 2 is an end elevation, showing the device in position within the smoke-arch of a locomotive-boiler.

Similar numerals of reference indicate corresponding parts in both views.

1 is the discharge-chute, having a central opening 1, at the top of which overhanging gates 3 3 are arranged. The said gates slide in the ways 16, in which they are secured, and range upwardly and inwardly, the ends of the respective gates partially closing the opening 1 in the chute when in normal position.

Upon the backs of the gates 3 are cast or otherwise attached the racks 11 11, which are engaged by toothed segments 10 10. The said segments are rigidly mounted upon the oscillating shafts 9 9, which are mounted in bearings 18, arranged upon the sides of the chute 1. The shafts 9 are respectively connected, by means of arms 8 8 and rods 5 5, with the oscillating lever 4, which is mounted upon the shaft 2. The inner end of the shaft 2 is mounted in a bearing 17, arranged upon the side of the chute 1, the outer end passing outward and through the side of the smoke-arch 14. To the end of shaft 2 is secured a lever 6, upon which is secured an adjustable s1eeveblock 12, which serves as a connection for the operating rod 7. The rod 7 leads to the reversing mechanism of the locomotive and is connected so as to move accordingly with the reversing-lever. It is obvious that when the rod 7 is moved the gates 3 would be actuated accordingly.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

In an exhaust-nozzle, in combination, a chute, sliding gates ranging oppositely in diverging planes and adapted to partially close the mouth of said chute, oscillating shafts having gear connections with said gates, a tilting bar having toggle-arms connecting its ends with said oscillating shafts respectively, and suitable means for actuating said tilting bar, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

' WILLIAM R. FREDERICK.
